-===
+#Introduction to the Node Ecosystem
 
-## Submission Instructions
-  * work in a fork of this repository
-  * work in a branch on your fork
-  * write all of your code in a directory named `lab-` + `<your name>` **e.g.** `lab-susan`
-  * submit a pull request to this repository
-  * submit a link to your pull request on canvas
-  * submit a question, observation, and how long you spent on canvas  
-
-## Resources  
-* [node assert docs](https://nodejs.org/dist/latest-v4.x/docs/api/assert.html)
-* [mocha docs](http://mochajs.org/#getting-started)
-
-## Requirements
-
-#### Configuration  
-<!-- list of files, configurations, tools, etc that are required -->
-* include the following:
-  * **README.md** - contains documentation about your lab
-  * **.gitignore** - contains a robust `.gitignore` file
-  * **.eslintrc** - contains the provided `.eslintrc` file
-  * **.eslintignore** - contains the provided `.eslintignore` file
-  * **.package.json** - contains all necessary dependencies and developer dependencies
-  * **lib/** - should contain your modules
-  * **test/** - should contain your unit tests
-
-#### Feature Tasks  
-* create a node.js module (`greet.js`) that exports a single function
-  * the `greet` function should have a single parameter that should expect a string as it's input
-  * the `greet` function should return the input name, concatenated with "hello <name>"
-  * the `greet` function should return `null` if the input is not a string
-* create a node.js module named `arithmetic.js`
-  * this module should have `add` and `sub` methods
-  * the `add` method should contain 2 parameters
-    * these parameters should be numbers and the method should return the sum of the 2 numbers
-  * the `sub` method should contain 2 parameters
-    * these parameters should be numbers and the method should return the first number minus the second number
-* decide on the expected behavior for non-number inputs
-
-#### Testing  
-* write a test the expects the greet module to return "hello world!"
-  * this should happen when invoked with "world!" as a parameter
-* write a test for the `add` and `subtract` methods on the arithmetic module
-  * this should ensure that your functions work with number inputs
-
-####  Documentation  
-* write a description of your project (this should be in your `README.md` file)
-
-###### BONUS 1pt
-* write a test that expects the greet module to return null when you use non string values
-* write a test that ensures the functions work as expected with non number inputs
-
-## Rubric  
-* 2pts configuration
-* 3pts feature tasks
-* 3pts tests
-* 2pts documentation
+##This project is an introduction to the concepts of writing simple response code for the back end, and writing tests to determine if they work as intended or not.  The greet.js file is a simple function that returns a greeting from whatever name parameter that is put into the function, and it requires the use of a string as well as some input.  The arithmetic.js file is an object that we created two methods for, an "add" and a "sub" method.  These are for adding and subtracting values that are put into their parameters.  The greet-test.js file is a file that tests to see if our greeting function is working as intended and our arithmetic-test.js is another test that ensures that the arithmetic functions that we have wrote behave properly.
